TWO-WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 285,793, dated October 2, 1883..

Application filed June 26.1883. (No model Be it known'that I, CHARLES W. BURGTORF,

a citizen of the United States, residing at Petaluma, in the county of Sonoma and State of California, have invented certain new and useful Improvements in Two Wheeled Vehicles, of which the following is a specification.

This invention relates to improvements in two-wheeled vehicles in which severed or divided shafts are employed; and the object of my invention is to provide a couplingfor such divided shafts which will be of simple construetion, easily applied, and not liable to get out of order, and also to provide a means whereby the body of the vehicle may be kept in a nearly horizontal positionand not be materially affected by the inclined position of the shafts proper, and to prevent the sudden and unpleasant pitching forward and backward of the vehicle body orbox when traveling upon uneven ground. These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view, representing my improvement applied'to the shafts of a vehicle. Fig. 2 is a top view of one of the severed shafts. Fig. 3 is a cross-section on line X X of Fig. 2. Fig. 4 is a cross-seetion on line Y Y of Fig. 2. Fig. 5 is a cross-section on line Z Z of Fig. 2. v Fig. 6 is a longitudinal section through the "end of one of the shaft-sections. Fig. 7 is a perspective view of one of the clips or holding-boxes.

Similar letters of reference are used toindicate like parts throughout the several views.

The shafts of my vehicle are made in two sections, and consist of rear portions, A, which form a support for the body of the vehicle, and forward portions or sections, A, between which the animal is placed. The meeting ends of the divided or severed shafts are placed side by side, as shown in Figs. 1

and 2, and are held in that position by clips or boxes and a pivotal pin. These boxes are made in the form shown .in Fig. 7, and are composed of a rectangular or oval box, a, to one side of which is riveted a plate or bar, 12, provided with bolt-holes and adapted to be secured upon the side of the shaft. If found more convenient, the box and its fastening although I prefer to make them of metal, yet

under some circumstances leatherwill be'fouiid I to answer very well for the end boxes. practice I prefer to employ three of these boxes upon each side of the vehicle, and the central one, (3, of each set is attached to the rear section of the shaft, and carries a bolt or pivot, D, which passes horizontally through both divisions of the shaft and is held in position by the usual head and nut. To the rear of this pivotal box, and upon the same section of shaft, I attach the box E, which receives the rear end of the forward section of the shaft. To the front, or in advance of the box 0, Iattach or connect to the forward section of the shaft the box F, which receives the forward end of the rear shaft-section.

It will be seen from the foregoing that the bolt or pivot D forms a hinge-joint for the severed shaft, and that while the clips or boxes prevent side play, they permit of a certain amount of vertical play of the two shaft-sec are provided with two or more leather waslv ers or buffers, G,which prevent undue jarring and rattling of the parts, and these leathers are held in place by bolts H, which pass through the boxes and ends of the shaft-sections. The holes in the shafts through'which they pass are elongated in the direction of the shafts length, as shown in Fig. 6, in order to admit of the necessary amount of play when the forward end of the shaft is raised or depressed; and in the event of the breakage of the pivotal bolt D these auxiliary bolts H will serve to retain the severed shafts in position until repairs can be made. Those portions of the shafts through which the bolts pass may be hushed with strapiron or plates, as shown at 0, Figs. 1 and 6.

Havingthus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

A A, theends of which overlap and are pivoted and held in place by an intermediate shaft, loop, or box,G, andpivot D, and the endboxes, E and F, secured upon the side face of one shaft-section and embracing the end of the adsubstantially as shown, and for the purpose IO joining shaft-section, substantially as shown, specified. and for the purpose shown and set forth. In testimony that I claim the foregoing I 2. In a twowheeled vehicle having severed have hereunto set my hand and seal. 7 5 or hinged shafts, the ends of which overlap the shaft loops or boxes herein described, 0011- CHARLES BURGTORF sisting of a shaft-receiving loop, a, forming \Vitnesses: 7 part of or rigidly connected to an attaching- WILMER BRADFORD, plate, I), and provided with suitable bo1t-holes, CHAS.
